[saihemanth-cloudera]

…VE-28967

What changes were proposed in this pull request?

Making the RELOAD event backward compatible

Why are the changes needed?

Clients like impala are unable to use HIVE-28967

Does this PR introduce any user-facing change?

No

How was this patch tested?

Remote cluster with Impala enabled

[dengzhhu653]

this method might return null somehow, will it break the compatibility? should we catch it on the impala side?

[saihemanth-cloudera]

I have added necessary guardrails on the Impala side to avoid this null pointer exception. i.e., if getPtnObj() returns null then we should check getPartitionObjs() method.

If the flagged items do not appear to be text

If items relate to a ...

• well-formed pattern.

  If you can write a pattern that would match it,
  try adding it to the patterns.txt file.

  Patterns are Perl 5 Regular Expressions - you can test yours before committing to verify it will match your lines.

  Note that patterns can't match multiline strings.

• binary file.

  Please add a file path to the excludes.txt file matching the containing file.

  File paths are Perl 5 Regular Expressions - you can test yours before committing to verify it will match your files.

  ^ refers to the file's path from the root of the repository, so ^README\.md$ would exclude README.md (on whichever branch you're using).
